The sulfonic acid polymer and/or linear polyacrylamide polymer is covalently bonded to the capillary wall and therefore is fully compatible with organic solvents such as acetonitrile and DMF. Essentially, the product has the same compatibility conditions as type A and B silica-based HPLC bonded phases. For example, it is known that strongly acidic conditions may cause hydrolysis of HPLC bonded phases. The same principles apply to the Zero and Controlled Flow Capillaries. With proper care, you can expect aout 80 hours of life for these capillary products.
• Temperature should not exceed 60 °C
• The pH range of the capillaries is 2.0–8.5
